I have not had my bag out into the backcountry but first impressions are it is made well, has lots of room, is very light and packs down well. My wife has an 800 fill bag with the same rating, when laid side by side her's has much more loft - so I am hoping it is as warm as advertised.

I just returned from 5 nights backpacking in the Sierra, sleeping in 25-35 degree temps in a tent. I sleep cold and it kept me warm with just a fleece on in the bag, but I had to have the thing really snugged up with just nose and eyes exposed to keep me warm. The bag is definitely warmer than my older 600 fill 15 degree bags and is much lighter and more compact. It does not appear to have the DWR finish of the Marmot Helium, nor the curved baffles. The draft tube is kind of wimpy and the hood is nothing special. I'm not sure if the Helium is worth $150+ more than this bare bones but functional bag. I may wish I had the DWR outer of the Helium but this one worked just fine on this trip and I only hope it is a durable as all my other Marmot gear.

Only used it for two nights so far. Slept very well Outside temps in the 50s had side sipper half open.
Very happy with this sleeping bag Highly recommend it.
I got a compression bag to use with it. Will not use the original bag that it comes with for anything.

I have used the bag several times in Shenandoah and will be using the bag soon in Peru. I'm a fan. I thought it would be too long (I'm 5'4") but when I'm tucked all the way inside it's actually the perfect amount of space. The left side zipper takes some getting used to. It is definitely a warm bag. Im a naturally cold person no matter the weather outside and haven't had problems staying warm yet! Stuff sack is small but it fits snugly into it.

I was amazed at how light this bag is and how well it packed down for the type of bag it is.
I bought this bag specifically for a Mt goat hunt where reducing the amount of weight that I am carrying is crucial. This bag is exactly what I was looking for....

This was my wife's first 800 fill sleeping bag. We have taken it out once already on a cross country skiing trip. It kept her warm and comfortable, outshining all other sleeping bags in the yurt. Moving up to this 800 fill is a great option if you are willing to invest.

Occasionally we are able to reorder a product, but closeout items are typically unable to be reordered. We suggest signing up for the My Updates as the best way to monitor incoming products. You will receive email notifications of our newest stock items.

Hi, Peter. Yes, I believe this is the same as the Marmot Helium. I don't know if it's highly water resistant because I have not yet gotten it wet. I love this sleeping bag though. It's very comfortable, packs up real small and weight is minimal compared to my EMS synthetic bag.

“I ordered this bag, BUT I just read a review that the the picture is NOT what is being sent to customers! Reports are coming in that the picture shows a full length zipper, but the bag only has a mid length zipper. What is true? IF I receive something other than what is pictured, then will you refund my shipping BOTH ways?”

About Marmot

Conceived in a university dorm room by a pair of climbing buddies, Marmot Mountain Works first opened its doors in the spring of 1974 in Grand Junction, Colorado. At the time, the base of operations was a 100-year-old stone building. That same year, the first Marmot down jacket was produced specifically for an action flick called “The Eiger Sanction,” starring legendary actor Clint Eastwood. In the four decades since, Marmot has continued to engineer reliable gear that exceeds the expectations of outdoor athletes. Today, Marmot tents, backpacks, outerwear, clothing and Marmot sleeping bags are still pushing the limits in the planet’s most challenging conditions, from the summits of the world’s highest mountains to the deepest river basins.
